The present disclosure is further described below with reference to thedrawings and embodiments.

The present disclosure is directed to the technical problem of a displaypanel of the prior art: While a screen-body ratio of a conventionaldisplay panel is increased, an area of a bezel is severely reduced,causing the driving chip to be too close to a display region and an edgeof a substrate, and thereby causing technical defects, such as poorelectrical properties and poor panel sealing, after the driving chip ismounted. The present embodiments can resolve the defect.

As shown in FIG. 1A-FIG. 1B, the display panel provided in thisdisclosure includes an array substrate 101 and a color filter substrate102 disposed opposite the array substrate 101. A surface of the arraysubstrate 101 is provided with a display region 103, and the displayregion 103 is defined by a frame sealant. A liquid crystal layer isdisposed inside the frame sealant, and the color filter substrate 102and the array substrate 101 are combined by the frame sealant.

The regions between the display region 103 and edges of the arraysubstrate 101 form a bezel 104, and the bezel 104 is provided withsignal traces and other electronic components, such as a driving chip105, a flexible circuit board 106, and the like.

The color filter substrate 102 is shorter than the array substrate 101,and the color filter substrate 102 is higher than a surface of the arraysubstrate 101. A step substrate 101 is formed between a projection of alower edge of the color filter substrate 102 projected onto the surfaceof the array substrate 101 and an edge of the array substrate 101. Thestep region is located in the bezel 104, other electronic components,such as the driving chip 105 and the flexible circuit board 106, arelocated in the step region, and the signal traces extend from the stepregion to the entire bezel 104 and the display region 103.

When a mother board of the display panel is being cut, a protrusion 107is reserved at an end of the array substrate 101 away from the displayregion 103, the protrusion 107 is located at a middle position of theend of the array substrate 101, and indents are respectively formedadjacent both lateral sides of the protrusion 107. The driving chip 105is disposed between a lower edge of the protrusion 107 and an edge ofthe display region 103, thereby raising the height between an upper sideof the driving chip 105 and the edge of the display region 103 and the aheight between a lower side of the driving chip 105 and the lower edgeof the protrusion 107.

The flexible circuit board 106 includes a connection section connectedto the bezel 104, a main body section bent to a back of the displaypanel, and a bending section connecting the connection section with themain body section. The bending section is located in the indents, and abending radius of the bending section is less than or equal to theheight of the protrusion 107.

In the embodiment of the present disclosure, the protrusion is disposedin accordance with the number of driving chips. The positions of theprotrusion and the driving chip are not limited to the middle positionof the bezel. For example, the protrusion may also be disposed close toany side of the bezel.

Therefore, compared with the display panel in the prior art, theembodiment of the present disclosure widens the spaces adjacent theupper and lower sides of the driving chip 105, without increasing theoverall height of the bezel 104, which not only solves the problem ofthe space around the driving chip 105, but also maintains the narrowbezel of the display panel in the prior art.

As shown in FIG. 2, the left picture is a display panel provided by thepresent disclosure, and the right picture is a display panel of theprior art. The left picture and the right picture each include an arraysubstrate 201, a display region 202, a driving chip 206, and a colorfilter substrate 204. The array substrate 201 includes a bezel 207including a height A between a lower edge of the display region 202 andan edge of the color filter substrate 204, a height B of the drivingchip 206, a height C between an upper edge of the driving chip 206 andthe edge of the color filter substrate 204. The left figure alsoincludes a height D of the protrusion 208, and a height E between alower edge of the driving chip 206 and an edge of the protrusion 208.The left FIG. 1 includes a height F between the lower edge of the colorfilm substrate 204 and an edge of the indent of the bezel 207, and theright figure includes a height F between the lower edge of the colorfilter substrate 204 and an edge of the bezel 207.

In the embodiment of the present disclosure, the overall height of thebezel=the height A+the height F+the height D, wherein the height A issubstantially equal to the height F, the difference between the height Aand the height F is less than 50 um, and the height D is greater thanthe difference between the height B and the height F. For example, theheight D is 5 to 6 times the difference between the height B and theheight F, thereby ensuring that the height C and the height E are notless than 100 um.

For example, refer to the specific arrangement as the following table:

Height/unit (um) FIG. A B C D E F Life Figure 700 780 200 400 120 700Right Figure 540 780 80 0 0 860

As can be seen from the above table, in the display panel of theembodiment of the present disclosure, the height of the protrusion 208is added, and the driving chip 206 is moved downwards, so that theheight A between the lower edge of the display region 202 and the edgeof the color filter substrate 204 and the height C between the upperedge of the driving chip 206 and the edge of the color filter substrate204 are both increased, and the height F between the lower edge of thecolor filter substrate 204 and the edge of the indent of the bezel 207is reduced, compared to that in the prior art. Under the case thatcurvature radiuses of the flexible circuit boards are the same, thecombined height of the bezel 207 and the bending section of the flexiblecircuit board after the flexible circuit board is bent in the embodimentof the present disclosure is smaller than that in the prior art, furthershortening the height of the bezel 207.

In one embodiment, in order to reserve enough space for gate on array(GOA) traces 205, fan-out wiring 203, and metal terminals, the distancebetween the edge of the driving chip 206 close to the display region 202and the edge of the display region 202 is determined to be greater thanthe distance between the edge of the driving chip 206 close to theprotrusion 208 and the edge of the protrusion 208.

For example, the driving chip 206 is disposed in the bezel 207 and islocated outside a region of the protrusion 208.

For another example, the driving chip 206 is completely or partiallydisposed in the region of the protrusion 208.

As shown in FIG. 3A, the display panel provided in the presentdisclosure includes an array substrate 301, a display region 302, acolor filter substrate 303, and a protrusion 304 formed at an end of thearray substrate 301. A driving chip 306 is disposed in a bezel 305 ofthe array substrate 301.

The protrusion 304 includes two symmetrically arranged short edgesconnecting edges of the bezel 305, and a long edge connecting other endsof the two short edges. For example, the short edges are straight edges,the short edges are perpendicular to the edges of bezel 305, and asurface shape of the protrusion 304 is rectangular.

The difference between the display panel provided in this disclosure asshown in FIG. 3B and that as shown in FIG. 3A is that the short edgesare straight edges, the angles formed between the short edges and theedges of the bezel 305 are non-right angles, that is, the angle isgreater than or less than 90 degrees, and the surface shape of theprotrusion 304 is trapezoidal.

The difference between the display panel provided in this disclosure asshown in FIG. 3C and those as shown in FIG. 3A and FIG. 3B is that theprotrusion 304 includes a convex arc edge, two ends of the convex arcedge connect the edges of the bezel 305, and the ends of the convex arcedge are in concave arc transitions.

As shown in FIG. 4A, the display panel provided in this disclosureincludes an array substrate 401, a color filter substrate 408, a bezel405 located in a non-display region of the array substrate 401, adriving chip 406 disposed in the bezel 405 and fan-out traces 403connecting the driving chip 406. For example, the fan-out traces 403 areused to transmit display data signals to the display region 402. Atleast one set of gate on array (GOA) traces 409 are disposed in thebezel 405. Take two sets of symmetric GOA traces 409 as an example. Twosets of the GOA traces 409 include a parallel segment located outsidethe display region 402 and being parallel to edges of the display region402, and an inclined segment located in the bezel 405 and towards thedriving chip 406. The inclined segment of the GOA traces 409 isconnected to the driving chip 406 to input gate signals, and theparallel segment of the GOA traces 409 is connected to a scan line ofeach pixel row to output the gate signals.

A plurality of metal terminals are disposed in the bezel 405 andconfigured for accessing signals of the flexible circuit board, and themetal terminals include at least a primary signal metal terminal group4071 and a secondary signal metal terminal group 4072. For example, theprimary signal metal terminal group 4071 includes pixel data signals andgate signals, the secondary signal metal terminal group 4072 includespower signal, etc. The primary signal metal terminal group 4071 isarranged close to the driving chip 406, and the secondary signal metalterminal group 4072 is arranged away from the driving chip 406 and theinclined section of the GOA traces 409.

Because the driving chip 406 is relatively moved down, and the inclinedsegment of the GOA traces 409 connected to the driving chip 406 is moveddown, too, thereby compressing the space where the metal terminals arearranged. If the metal terminals are too close to the GOA traces 409,the impedance increases, a signal distortion is caused, and the displayquality is affected. Therefore, in the embodiment of the presentdisclosure, at least a part of the metal terminals are disposed awayfrom the GOA traces 409.

In an embodiment, the secondary signal metal terminal group 4072 and theprimary signal metal terminal group 4071 are separately disposed, andthe main signal metal terminals are completely or partially located inthe protrusion 404, and the secondary signal metal terminals are locatedoutside the region of the protrusion 404. The distance between the metalterminals and the GOA traces 409 is effectively controlled, and theimpedance is reduced.

As shown in FIG. 4B, the flexible circuit board includes a main bodysection 4101 and a connection section for connecting the metalterminals. The connection section includes a first block 4102correspondingly connected with the primary signal metal terminal group4071, and a second block 4013 correspondingly connected with thesecondary signal metal terminal group 4072, and the first block 4012 isoffset from the second block 4013.

As shown in FIG. 4C, compared with the arrangement of the metalterminals in FIG. 4A, the metal terminals are closely arranged. Theprimary signal metal terminal group 4071 and the secondary signal metalterminal group 4072 are both disposed outside the region of theprotrusion 404, thereby avoiding the reduction of the space of theprotrusion 404. The area of each of the metal terminals in the primarysignal metal terminal group 4071 is equivalent to the area of each ofthe metal terminals in the secondary signal metal terminal group 4072,to ensure a stable connection of signal contact points.

In an embodiment, a height of each of the metal terminals of the primarysignal metal terminal group 4071 is lower than a height of each of themetal terminals of the secondary signal metal terminal group 4072, and awidth of each of the metal terminals of the primary signal metalterminal group 4071 is wider than a width of each metal terminal of thesecondary signal metal terminal group 4072. The distance between themetal terminals and the GOA traces 409 is maintained by reducing theheight of the metal terminals close to the GOA traces 409, therebyreducing the impedance.

In an embodiment, a height of each of the metal terminals in the primarysignal metal terminal group 4071 gradually lowers from the metalterminals away from the driving chip 406 and the inclined segment of theGOA traces 409 to the metal terminals close to the driving chip 406 andthe inclined segment of the GOA traces 409, and a width of each of themetal terminals in the primary signal metal terminal group 4071gradually increases from the metal terminals away from the driving chip406 and the inclined segment of the GOA traces 409 to the metalterminals close to the driving chip 406 and the inclined segment of theGOA traces 409, for ensuring the same distance between each of the metalterminals and the GOA traces.

As shown in FIG. 4D, the flexible circuit board includes a main bodysection 4101 and a connection section 4104 for connecting the metalterminals, an end of the connection section 4104 has a regular geometricshape, the end of the connection section 4104 is provided with a firstconnection region and a second connection region, the first connectionregion covers and connects the primary signal metal terminal group, andthe second connection region covers and connects the secondary signal.

In an embodiment, a virtual metal terminal group is further disposed inthe bezel 405, and the virtual metal terminal group is located adjacenta lateral side of the secondary signal metal terminal group 4072 awayfrom the driving chip 406 and the inclined segment of the GOA traces409.

The beneficial effects of the present disclosure is as follows: comparedwith the existing display panel, the display panel provided by thepresent disclosure is provided with the protrusion at the end of thearray substrate, and the driving chip is provided in the space betweenthe display region and the protrusion, thereby increasing the distancebetween the driving chip and the edge of the display region and thedistance between the driving chip and the edge of the bezel, andpreventing the technical defects that the area of the bezel in a displayscreen with a high screen-body ratio is compressed, causing the drivingchip to be too close to the display region and an edge of the substrate,and thereby causing poor electrical properties, and poor sealing of theliquid crystal cell after the driving chip is mounted. Moreover, abending section of the flexible circuit board is located in flat regionsadjacent both lateral sides of the protrusion, and the thickness of thebending section does not exceed the edge of the protrusion, so a widthof the bezel is not increased, and the screen-body ratio of the displaydevice is maintained.
